Design/Looks

RAB® Board is a pre-sealed rigid air barrier for use behind cavities in medium to high-rise facade constructions. It forms part of a drained and ventilated cavity or rainscreen systems and helps in equalizing the wind pressures within a cavity to that experienced on a building fašade. It is normally used in specific engineering design projects.

RAB® Board also forms an effective drainage plane which helps in draining moisture. The acrylic sealer applied on RAB® Board surface acts as moisture repellant and prevents the timber frame from moisture.

Features/Benefits

Prevents the frame from being exposed to air leakage due to high wind pressures.
Provides a drainage plane to manage moisture within a cavity.
Painted green for easy identification on site.
RAB® Board is suitable to resist high wind pressures within the cavities.
Provides excellent temporary weather protection before final cladding is erected.
RAB® Board also achieves good bracing values.
Product warranty of 15 years.
